Professor McFerran has been teaching logic at the college level for more than fifty years. During that time he has published several books presenting a formal logic using a postfix literal notation and a natural deduction proof system. This new workbook is intended for high school students and presents special techniques to advance a skill in critical reasoning. It may also prove useful for college classes in critical thinking as well as being the first part of a transferable college course in symbolic logic, to be supplemented with a conversion to a standard notation and additional material on two-place predicates.
